A totally waterproof layer that doesn’t make you overheat sounds too good to be true, but Cotopaxi prove it’s possible with the Parque jacket. Its seams are fully taped and every edge is trimmed with either a zip, drawstring or Velcro tab to keep even the heaviest of showers out. The nylon fabric is breathable and fitted with adjustable underarm vents, though, so you can keep moving comfortably through the bad weather.
